ABSTRACT

922,743. Doffing-coils of filamentary material. ETABLISSEMENTS G. DECOMBE. Jan. 21, 1960 [March 23, 1959], No. 2265/60. Class 120 (2). A spool arrangement on which a coil of wire, cable, thread or the like may be wound comprises a flange 2 revolvably mounted in a stationary wall 4, an axially movable flange 11 and an axially movable core drum 5. When a coil 6 is fully wound the core 5 is retracted by a shaft 8 sliding in a portion 12 of a unitary member 11, 10, 12, 13. During this retraction the wall 7 of the core contacts the vertical wall of the member 11, 10, 12, 13 and axially displaces it against the spring 14 to the position shown in Fig. 4. The coil 6 then drops away between the stationary walls 15, 16 preferably to be guided by a hopper arrangement into a box for immediate packing: a pusher member may be provided to assist in removing the coil. The spool arrangement is driven at the pulley 13, the core 5 and flange 2 being driven by friction from the member 11, 10, 12, 13. In a further form the coil receiving drum is mounted on a spindle which may be retracted therefrom to allow the coil to fall away with its receiving drum still inside. Means may also be provided for adjusting the spacing of the flanges 2 and 11 and of the stationary walls 15 and 16.

(Cl. 242-81) Coils of wires, cables and threads are generally obtained by winding the latter over a disconnectable spool, so as to allow an easy removal of the coils obtained.

Upon stoppage of the forming spool, the operations to be executed for the removal of the coil are approximately as follows:

Release of one of the flanges of the forming spool.

Shrinking or collapsing of the drum of said spool.

Removal of the released flange.

Removal of the coil.

Resetting of the movable flange in its starting position.

Locking of said flange in said position.

Expansion of the drum into starting conditions.

These operations are executed by hand in a frequently repeated manner and they are consequently very tiring for the operator. Furthermore, they last some time and this leads to a waste of time-which is comparatively important, since the complete cycle of coiling operations is comparatively short.

The arrangement according to the invention for the removal of a coil of wire, cable or thread wound over a forming spool in accordance with the present invention allows reducing substantially the loss of time, whereby the productivity is increased.

To this end, the two flanges of the forming spool cooperate with stationary surfaces, in substantial alignment therewith and between which the coil which has just been executed is to slide out after cutting out of the connections holding the coil in position, which connections are constituted by the drum round which the coil is wound and by the pressure exerted by the coil on the inner surfaces of the flanges of the forming spool.

The accompanying diagrammatic drawings illustrate, by way of example, a preferred embodiment of the improved arrangement. In said drawings:

Fig. 1 is a longitudinal sectional view through line 11 of Fig. 2 of the arrangement as shown during the winding of a coil.

Fig. 2 is a transverse cross-section through line 2-2 of Fig. 1.

Fig. 3 is a longitudinal cross-section showing the location of the difierent parts of the arrangement, after an outward shifting of the drum out of the forming spool.

Fig. 4 is a similar longitudinal cross-section showing how the coil may be removed after removal of the drum out of the forming coil and shifting aside of one of the flanges.

The forming spool includes a stationary flange 2 carried by the spindle 3 revolvably mounted in the wall 4 of the casing. The inner surface of said flange forms a bearing for one of the edges of the cylindrical wall of the spool drum 5 over which the material 6 is Wound. Said drum is rigid through its bottom 7 facing away from the wall 4 with a control rod 8 which serves for axially shifting the drum. The peripheral surface of the drum 5 slides freely inside the inner wall of the chamber 9 which serves as a housing for the drum. The cylindrical nited States Patent wall 10 of said chamber is rigid with a movable transverse flange 11 and also with a carrier or sleeve 12 fac ing away from the inside of the chamber and carrying the pulley 13' through which the spool drum 5 is driven into rotation. A spring 14 acting on the outer transverse closing surface of the chamber 9 urges the latter towards the flange 2 together with the movable flange 11 rigid with said chamber and sleeve.

After the winding of the coil over the drum and in order that said coil may drop through the channel separating two stationary walls 15 and 16 forming substantial extensions of the corresponding flanges 2 and 11 of the coil-forming spool, it is necessary to make the drum 5 recede and to shift apart said flanges 2 and 11.

The drum 5 may be urged out of the formed coil into the bottom of its housing or chamber 9 (Fig. 3) under the action of the control rod 8 which is shifted to this end in the direction of the arrow 17. When the drum 5 has completely receded inside said housing 9, it may be 'urged further in the same direction defined by the arrow 17, whereby its bottom 7 draws along with it the cooperating outer wall 10" of the chamber 9 together with the flange 11. Said movement increases, as illustratedin Fig. 3, the spacing between the flanges 2 and 11 and releases consequently the coil 6 which is no longer subjected to any lateral pressure. Since the drum has now executed its receding movement, the coil is no longer held and drops through the channel 18 between the walls .15 and 16, the opening into said channel being completely released since the movable flange 11 of the forming spool is set in alignment with the stationary wall 16 and engages a recess 19 formed for this purpose in the said wall 16.

It is also possible in case the weight of the coil may not be sufficient to make it drop freely through the channel 18 or to slide over one side thereof, to provide a pusher member, which is not illustrated, so as to further this dropping or sliding movement.

The channel 18 may also be provided with lateral defleeting members 20 (Fig. 2), the position of which is adjustable and which form the side walls of a hoppershaped structure through which the coil may slide or be pushed.

Assuming a basket, box or the like container is positioned under the foot of the hopper or channel, the coil may be immediately inserted'in a package at the output of the winding machine.

Obviously, instead of resorting to a laterally shiftable drum round which the wire, cable or thread is to be wound, it is possible to provide a mere spindle engaging a spool body, the breadth of which is equal to that of the coils to be formed and which is brought into a suitable position to allow the winding of the material over it. The result is that, upon removal of the spindle, the coil will drop or be pushed through the channel or hopper together with the spool body carrying it.

In practice and in order to allow a suffieiently broad range of operation, the coil-removing arrangement which has just been described may include means for adjustingthe spacing between the flanges 2 and 11 and that between the stationary walls 15 and 16.

Obviously, the invention is by no means limited to the sole embodiment which has just been described and it covers all the modifications thereof falling within the scope of the accompanying claims. In particular, other means may be provided for shifting aside the drum of the forming spool and for spacing apart the flanges of said spool, with a view to obtaining a speedy removal of the coil which has been formed.
